But many designs have DFM problems, the factory can not produce it well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DFM means Design for Manufacturability. It is the rules to make your board easy to produce.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"575\" src=\"https:\/\/pcbworldlink.com\/blog\/wp-content\/uploads\/2026\/11\/bad-vs-good-design-1024x575.jpg\" alt=\"\" class=\"wp-image-29\" srcset=\"https:\/\/pcbworldlink.com\/blog\/wp-content\/uploads\/2026\/11\/bad-vs-good-design-1024x575.jpg 1024w, https:\/\/pcbworldlink.com\/blog\/wp-content\/uploads\/2026\/11\/bad-vs-good-design-300x169.jpg 300w, https:\/\/pcbworldlink.com\/blog\/wp-content\/uploads\/2026\/11\/bad-vs-good-design-768x431.jpg 768w, https:\/\/pcbworldlink.com\/blog\/wp-content\/uploads\/2026\/11\/bad-vs-good-design-1536x863.jpg 1536w, https:\/\/pcbworldlink.com\/blog\/wp-content\/uploads\/2026\/11\/bad-vs-good-design-2048x1151.jpg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">{&#8220;source_type&#8221;:&#8221;douyin_beauty_me&#8221;,&#8221;data&#8221;:{&#8220;anchor_info_items&#8221;:[{&#8220;type&#8221;:&#8221;image_template&#8221;,&#8221;id&#8221;:&#8221;&#8221;}],&#8221;os&#8221;:&#8221;ios&#8221;,&#8221;editType&#8221;:&#8221;image_edit&#8221;,&#8221;exportType&#8221;:&#8221;image_export&#8221;,&#8221;pictureId&#8221;:&#8221;43165247-93FF-43D1-AA9D-22F30ACE916B&#8221;,&#8221;product&#8221;:&#8221;lv&#8221;}}<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Here are some common DFM mistakes we see every day:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Trace width and space too small. If the line is too thin, copper may break. Small gap will cause short circuit.<\/li>\n\n\n\n<li>Pad size not match component. Pads too small, the part can not solder well.<\/li>\n\n\n\n<li>No enough clearance near hole and slot.<\/li>\n\n\n\n<li>Copper area without thermal relief, easy to have bad soldering.<\/li>\n\n\n\n<li>Outline too close to traces, easy damage when cutting.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">These small problems will make your PCB sample rejected. You need rework design, waste time and money.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are not sure your design is ok, you can send your Gerber file to us. We can check DFM for you before production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Contact us for your PCB and PCBA order.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When you finish your PCB design, you may think it can b [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-28","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/posts\/28","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/comments?post=28"}],"version-history":[{"count":1,"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/posts\/28\/revisions"}],"predecessor-version":[{"id":30,"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/posts\/28\/revisions\/30"}],"wp:attachment":[{"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/media?parent=28"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/categories?post=28"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pcbworldlink.com\/blog\/index.php\/wp-json\/wp\/v2\/tags?post=28"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
